Application filed February a, 1915. Serial at. 6.658.

To all whom it may concern: I I Be it known that I, JERRY E. GREGG, acitizen ofthe United States, residing at Gloudcroft, in the county ofOtero and State of .New Mexico, have invented certain new plus thefriction of such machinery, as is.

used in the operation of the pump, in order to lift the water anddischarge the same from the well or reservoir.

It is a further object of my invention to provide an improvedconstruction and arrangement of the pump valves whereby they may bereadily assembled and connected to the lower end of the pump barrel andlowered into the well, and aseat orsupport connected to the lower end.of the well casing upon which the valve mechanism normally rests and issupported, whereby said mechanism maybe bodily removed from the casingfor the purpose of repair, without necessitatin the removal. of saidcasing.

It 1s an additional object of my invention to produce a very .eflicient,durable and serviceable pump mechanism which may be manufactured andsold at comparatively small cost.

With the above and other objects in view, my invention consists in thenovel features of construction, combination, and arrangement of parts tobe hereinafter more fully described, claimed, and illustrated in theaccompanying drawing, in which,

Figure 1 is a vertical section through the lower end of the well casing,showing my improved pump valve mechanism arranged therein and the lowervalve in open pos1-- tion; Fig. 2 is a similar view, the lower valve bmgclosed and the upper valve open; Fig. 3 is a section taken on the line33 of Fig. 1 and Fig. 4 is a section take on the line 4-4 of Fig. 1.

Referring in" detail to the drawing, 5

designates the well casing which' is preferably constructedof sheetmetal and is provided upon its lower end with exterior screw threads. Arelatively thick metal sleeve 6 is also provided with exterior. screwthreads 7 on its upper end and extends below the well casing toconstitute and effect a continuation thereof. This sleeve is connectedto the threaded lower end of the casing 5 by means of an interiorlythreaded collar 8. It will thus be seen that the upper end of the sleeve6 produces anannular mw-ardly projecting shoulder or seat 9 at the lowerend of the casing 5.

A pipe or tube'lO is adapted to be coupled or connected in any approvedmanner at its upper end to the pump barrel, (not shown); Through thistube and the pump barrel, the piston rod 11 extends, and the lower endof said rod is equip ed with a piston 12 which snugly fits within the pie 'or tube 10 for reciprocatory movement. T e

internaldiameter of the pipe 10' at its lower end, is reduced, and suchreduced portion provided with interior screw threads indi'- cated at 13.

A cylinder 15 is adapted to snugly fit within the sleeve 6', and theupper end of this cylinder is diametrically enlarged, as indicated at16, and'the lower endof such enlarged portion is adapted to seat u onthe shoulder 9 at the upper end of the s eeve 6. A packing ring,indicated at 17, is preferably interposed between the abutting ends ofthe cylinder enlargement 16 and the sleeve 6 to provide a substantiallyfluid-tight joint. The enlarged end 16 of the cylinder 15 is alsointeriorly threaded, as at 18, to receive the exteriorly threaded valvecasing 19. This valve casing includes an outer cylindrical body wall andan inner cylindrical wall 20 which is arranged in spaced concentricrelation to said outer wall and is extended beyond one end of the valvecasing in the form of a pipe or tube 21. The extremity of this tubularextension of the valve casing is exterior-1y threaded for engagementwith the interior threads on the tension 21 of the valve casing, thevalve member 23 is loosely engaged and is adapted to freely move uponsald extension between the upper end of the valve casing and the lowerend of the pipe 10. This valve memher, when in its normal position,extends over the webs 22 and rests upon the outer wall 19 of the casing,thus closing the upper ends of the spaces between said webs.

The lower end of the body of the cylinder 15 is interiorly threaded toreceive the removable valve casing 24 which is of somewhat similarconstruction to the upper valve casing above described, and includesacentral rod or stem 26 which projects upwardly beyond the end of thevalve casing and is connected, by means of aseries 01E radially disposedWebs 27, to the outer body wall of the casing. The upper end of the stem26 is threaded to receive a stop nut 28. The valve member 29 is looselyengaged upon said stem for vertical movement between the casing 24 andthe bottom face of said nut. This valve member is of somewhat lessdiameter than the internal diameter of the cylinder 15, so as to permitof the free passage of water upwardly around said valve member when thesame is in its open position, as shown in Fig. 1.

In assembling the several parts of my improved pump, the supportingsleeve 6 is first connected to the lower end of the well casing by meansof the collar 8, and said support and casing then lowered into the wellor reservoir from which the water is to be elevated. After the pipe ortube 10 has been connected to the pump barrel, the extension 21 of thecasing of the upper valve is threaded into the lower end of said pipe,the check valve member 23, of course, being first disposed upon theextension 21 of the valve casing. The upper enlarged end of the cylinder15 is now threaded upon said valve casing. The lower valve casing isthen threaded into the lower end of the cylinder, the check valve 29being properly arranged upon the stem 26. The assemblage of the severalparts is now completed, and the pipe or tube 10, together with the pumpvalve mechanism, which is connected thereto, is lowered into the wellcasing until the enlarged upper end of the cylinder 15 seats upon theupper end of the supporting sleeve 6 which is connected to the wellcasing 5. The plunger or piston 12, fastened to the rod 11, is thenextended downwardly into the pipe 10 and the pump is in condition foroperation. Assuming that the several parts have been thus connected andthe valve mechanism lowered into the water and upon the supportingsleeve 6, in the reciprocation of the piston or plunger 10 in its upwardstroke, the lower valve member 28 is lifted upon the stem 26 and wateris drawn u wardly through the spaces between the we s 27 of the lowervalve casing and into the cylinder 15 and the inner tube 21 of the uppervalve casing. In the reverse or downward stroke of the plunger 12, wateris expelled from the tube 21, and the check valve 29 having returned toits closed position, this water will be forced upwardly through thespaces between the webs 22 of the upper valve casing, thereby liftingthe valve member 23 upon the tube 21 until the same engages the lowerend of the pipe 10. p The water thus passes around said valve member andupwardly through the casing 5 from which it is expelled. By my improvedarrangement of the several elements, it will be seen that, in theoperation of the pump, all surplus weight and lost motion is overcome,and only sufiicient power is necessary to overcome the actual weight ofthe water and the friction which is a necessary incident to theoperation of the pump mechanism. When it is desirable, for any reason,to remove the pump valves from the casing 5, this may be easily andquickly done by simply lifting the pump barrel. As the same is drawnupwardly through the casing 5, both of the valves and the cylindricalwater receiving chamber 15 are also removed. Thus, it is unnecessary towithdraw the well casing. The several parts can be very easily andquickly assembled or disassembled and replaced at a nominal expense.

From the foregoing description, it will be seen that I have devised avery simple and efficient valved pump which may be em-' ployed byfarmers and others for the pumpmg of water for stock, irrigation orother purposes.

It will be apparent that the principle above disclosed may be embodiedin pumps of various sizes and capacity. The form, proportion, andarrangemnt of the several elements employed may also be greatly variedwithout departing from the essential featuresor sacrificing any of theadvantages of the invention, as embodied in the ap' pended claims.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is 1. In combination, a well casing, a supportconnected to the lower end of said wellcasing, upper and lower valvesarrangedin the well casing, said upper valve including a tubularextension and a valve member loosely engaged upon said extension forvertical movement, and a plunger cylinder con-- nected to said extensionwhereby the valves and the water chamber may be bodily removed from thewell casing, said cylinder constituting a stop to limit the upwardmovement of the valve member.
